Globally, the GHG emissions from producing beef is on average more than a hundred times greater than those of soy products per unit of protein.

first category focuses on economic policies aimed at raising the price of carbon dioxide (and other GHG) emissions or subsidizing the cost of carbon-free energy sources. The goal of a carbon price is to have the economic cost of burning hydrocarbons (coal, oil, and natural gas) reflect the actual harm their emissions cause to humans and society.

would burn all of our known fossil fuel reserves, since that would mean warming beyond 6°C (11°F) and an irreversibly ruined climate that would have trouble sustaining 1 billion people. It would also mean that (1) the Earth ends up with very large areas that are uninhabitable or unfarmable and (2) the ocean would suffer a mass extinction, with
